' UNITED. STATES JOHN OYRILLE LARKIN, OF VVHITEFIELD, NEW HAMPSHIRE,ASSIGNOR OF ONE-THIRD TO THOMAS GREY, OF SAME PLACE.

BRAKE-SHOE.

SPECIFICATION forming part of Letters Patent No. 319,731, dated June 9,1885.

Application filed November 15, 1884. (No model.)

To all whom it may concern:

Be it known that 1, JOHN OYRILLE LARKIN, a citizen of the Dominion ofCanada, residing at Whitefield, in the county of Coos and State of NewHampshire, have invented certain new and useful Improvements in BrakeHeads and Shoes for Railroad-Oars; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

Thisinvention relates to an improved brake head and shoe forrailroad-cars; and it consists in the construction, arrangement, andcombination of parts, as hereinafter more specifically described andclaimed.

In the annexed drawings, illustrating the invention, Figure 1 is a sideview of my improved brake head and shoe in position. Fig. 2is alongitudinal section of the same. Fig. 3 is a perspective View of thebrake-head. Fig. 4is a perspective View. of the brake-shoe, and Fig. 5is a section on the line 00 x of Fig. 2.

Like letters of reference designate like parts in the several views.

The outer side of the brake-head A is provided with jaws a a forreceiving the brakebeam, as shown by dotted lines in Fig. 1, a centralperforation being formed in said brakehead midway between the jaws, forthe passage of the retainingbolt by which the brakebeam is secured. Thelower portion of the brake-head is curved forward and is provided at itsend with a T-shaped slot or opening, 12, Fig. 3, for the reception ofalug on the lower portion of the brake-shoe. The upper end of thebrake-head is enlarged, and is provided with ahorizontal open-endedslot, 0, the closed end of which is slightly enlarged for receiving thehangers B, by which the brake-head and attached parts are suspended fromthe car. In the lower part of the slot 0 is a rectangular depression orrecess, d, arranged transversely, one end of said recess being open andthe other end closed, as shown in Fig. 3.

Above the slot 0 is pivoted a turn-buckle, O,

for securing the brake-shoe after the same has been placed in position.

The brake-shoe D is curved in the usual manner from end to end, as shownin Figs. 1, 2, and 4. Near its lower end on the rear side is a stud, 6,having a disk-like head that enters the T-shaped opening 12 in the lowerend of the brake-head, as before mentioned. The upper portion of thebrake-shoe on its rear side is nearly straight-faced, and is providedwith an L-shaped or rectangular-flanged lug, f, that enters the slot 0and recess din the upper end of the brake-head. It will be observed thatthe verticallyflanged portion of this lug is cut away at one end, (seeFig. 4,) so as to fit accurately within the recess d, while thehorizontal portion of the lug covers the closed end of said recess whenthe parts are connected.

On the outer end of the lug f is a pin or stud, g, and a beveledprojection or double incline, h, said pin and double-inclined projectionserving to retain the turn-buckle G'in place when the latter is turneddown to secure the brake-shoe.

In Figs. 1 and 2 the connection of the brake head and shoe is clearlyshown. Fig. 1 also shows the manner of suspending the parts from thecar-body. V

It will be seen that in order to connect the brake-shoe to the head orblock A, it is only necessary to slip the disk-headed stud 6 intotheT-shaped slotb at the lower end of the brakehead, and then slip thelug f at the upper end of the shoe sidewise into the slot 0 and recess01 at the upper end of the brake-head. The parts are now secured bydropping the turn-buckle O and forcing it over the double incline hun-'til it hangs between the latter and the pin 9, said pin and inclinepreventing the turnbuckle from becoming displaced by the jarring motionof the car.

To disconnect the parts, the turn-buckle O is forced back over thedouble-inclined projection h, and the upper end of the brake-shoe D isthen swung sidewise out of engagement with the brake-head. The parts canthus be readily detached and replaced with great facility and withoutrequiring the use of any special tool. It is also obvious that owing toIOC the mode of connection, as described, the shoe cannot become fixedby dust packing into the cavities or recesses at the points ofconnection with the brake-head.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the brake-head A,

. having T-shaped slot 6, horizontal slot 0, and

recess (1, the brake-shoe D, having a headed stud, e, and a flanged lug,f, provided with pin 9 and double incline h, and the turnbuckle G,pivoted in the upper end of the brakehead, substantially as shown anddescribed.

2. The combination of the brake-head A, 15 having jaws a a forattachment to the brakebeam, and provided with slots b a and recess d,the brake-shoe D, having stud e, and flanged lngf, provided with pin 9and incline h, the turn-buckle O, and the hanger B, substantially asshown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN CYRILLE LARKIN.
